4. Relevant information:
There are four data sets representing different conditions of an experiment.
All have the same attributes.
a. adult-stretch.data Inflated is true if age=adult or act=stretch
b. adult+stretch.data Inflated is true if age=adult and act=stretch
c. small-yellow.data Inflated is true if (color=yellow and size = small) or
d. small-yellow+adult-stretch.data Inflated is true if
(color=yellow and size = small) or (age=adult and act=stretch)
5. Number of attributes: 4
6. Number of Instances: 16
7. Attribute Information: (Classes Inflated T or F)
Color yellow, purple
size large, small
act stretch, dip
age adult, child
inflated T, F
